Abstract

A sewing machine includes an embroidery frame moving device that moves an embroidery frame holding a work cloth, an image pickup device that picks up images of an upper surface of a bed portion of the sewing machine, a position information storage device that stores position information indicating predetermined positions to which the embroidery frame is to be moved, a partial image acquisition device that causes the embroidery frame moving device to move the embroidery frame to the respective predetermined positions indicated by the position information, causes the image pickup device to pick up images at the respective predetermined positions, and acquires the images picked up by the image pickup device as partial images, and a composite image generation device that generates a composite image by combining the partial images acquired by the partial image acquisition device.

What is claimed is: 
     
       1. A sewing machine comprising:
 an embroidery frame moving device that is configured to accommodate any one of a plurality of embroidery frames that are different in at least one of size and shape and that moves an embroidery frame holding a work cloth; 
 an image pickup device that can pick up an image of an upper surface of a bed portion of the sewing machine; 
 a position information storage device that stores position information for each of the plurality of embroidery frames, the position information indicating predetermined positions to which each of the plurality of embroidery frames is to be moved; 
 a partial image acquisition device that:
 causes the embroidery frame moving device to move the embroidery frame to the respective predetermined positions indicated by the position information corresponding to a type of the embroidery frame detected from the plurality of embroidery frames, 
 causes the image pickup device to pick up images at the respective predetermined positions, and 
 acquires the images picked up by the image pickup device as partial images; and 
 
 a composite image generation device that generates a composite image by correcting, based on a thickness of the work cloth, the partial images acquired by the partial image acquisition device and combining the partial images that have been corrected. 
 
     
     
       2. The sewing machine according to  claim 1 , further comprising:
 a parameter storage device that stores a parameter to be used for adjusting the images picked up by the image pickup device; and 
 a partial image adjustment device that adjusts the partial images by using the parameter stored in the parameter storage device. 
 
     
     
       3. The sewing machine according to  claim 1 , wherein the composite image generation device generates the composite image by using at least a part of the respective partial images. 
     
     
       4. The sewing machine according to  claim 1 , wherein the composite image generation device generates the composite image by combining the partial images based on the predetermined positions stored in the position information storage device. 
     
     
       5. The sewing machine according to  claim 1 , further comprising:
 a display device that displays the image; 
 a first display control device that displays at least a part of an embroidery area and an embroidery pattern on the display device, the embroidery pattern being a pattern to be embroidered, and the embroidery area being an area in which embroidery sewing can be performed and the composite image is displayed as a background; 
 an embroidery position specification device that specifies a position as an embroidery position in the at least a part of the embroidery area displayed on the display device, the embroidery position being a position on the work cloth at which the embroidery pattern is to be arranged; 
 a second display control device that displays the embroidery pattern at the embroidery position specified in the at least a part of the embroidery area in which the composite image is displayed as the background; and 
 an embroidery data changing device that changes embroidery data based on the embroidery position of the embroidery pattern displayed on the display device, the embroidery data being prepared beforehand for embroidering the embroidery pattern. 
 
     
     
       6. The sewing machine according to  claim 5 , further comprising an embroidery pattern edit instructing device that instructs at least one edit operation of enlarging, reducing, rotating, flipping, and transforming on the embroidery pattern arranged in the at least a part of the embroidery area displayed with the composite image as the background on the display device. 
     
     
       7. The sewing machine according to  claim 1 , further comprising an embroidery data creation device that creates embroidery data for embroidering a target shown in the composite image. 
     
     
       8. The sewing machine according to  claim 1 , wherein the image pickup device is a CMOS image sensor. 
     
     
       9. A non-transitory computer-readable medium storing a computer-executable control program executable on a sewing machine, the program comprising instructions for:
 moving an embroidery frame holding a work cloth to respective predetermined positions that are indicated by position information corresponding to a type of the embroidery frame detected from a plurality of embroidery frames that are different in at least one of size and shape and to which the embroidery frame is to be moved; 
 acquiring images picked up at the respective predetermined positions as partial images; and 
 generating a composite image by correcting, based on a thickness of the work cloth, the partial images acquired and combining the partial images that have been corrected. 
 
     
     
       10. The non-transitory computer-readable medium according to  claim 9 , wherein the program further comprises instructions for adjusting the partial images by using a parameter for adjusting the picked up image. 
     
     
       11. The non-transitory computer-readable medium according to  claim 9 , wherein the composite image is generated by using at least a part of the respective partial images. 
     
     
       12. The non-transitory computer-readable medium according to  claim 9 , wherein the composite image is generated by combining the partial images based on the predetermined positions. 
     
     
       13. The non-transitory computer-readable medium according to  claim 9 , wherein the program further comprises instructions for:
 displaying at least a part of an embroidery area and an embroidery pattern, the embroidery pattern being a pattern to be embroidered, and the embroidery area being an area in which embroidery sewing can be performed and the composite image is displayed as a background; 
 receiving a specification that specifies a position as an embroidery position in the at least a part of the embroidery area displayed, the embroidery position being a position on the work cloth at which the embroidery pattern is to be arranged; 
 displaying the embroidery pattern at the specified embroidery position in the at least a part of the embroidery area in which the composite image is displayed as the background; and 
 changing embroidery data prepared beforehand for embroidering the embroidery pattern, based on the embroidery position of the embroidery pattern displayed. 
 
     
     
       14. The non-transitory computer-readable medium according to  claim 13 , wherein the program further comprises instructions for receiving an instruction that instructs at least one edit operation of enlarging, reducing, rotating, flipping, and transforming on the embroidery pattern arranged in the at least a part of the embroidery area displayed with the composite image as the background.
